Hasn't a clue about Michigan football coach Jim Harbaugh. "What does he do?" she asks.

Isn't sure she'd ever eat a coney dog. "It's not the first thing that comes to mind,'' she says.

How do I know all this? Because I'm on the phone with homemaking genius Stewart, the most self-aware (in that I'm-in-on-the-joke-kind-of-way), most competent, most meticulous human ever. A woman who pays so much attention to detail that she hand-washes her chickens before they make public appearances. "It’s not hard," she insists. "You hold them the right way ... warm soapy water and you wash them and rinse them really, really, really well and you blow dry them with a blow dryer. They're fine."

Anyway, she called me (well, she called via her publicist) to chat about headlining the Sept. 16 Detroit Free Press Food & Wine Experience. Scheduled to take place in Campus Martius, the event will feature, food, food and more food — plus cooking demonstrations, wine tastings and — tah dah — Stewart. "We've sold thousands of tickets for the whole event,'' she says. Click here for info.

She's been struck by the way Detroit is rebounding. "What I like is the vibe of the young entrepreneur,'' she says. "It’s exciting to me to visit many of the young companies to see the enthusiasm with which they are working."

Speaking of Maine, Stewart says her friends there are "dying" for Snoop Dogg — rapper, marijuana enthusiast, friend and costar of the slyly entertaining "Martha and Snoop's Pot Luck Dinner Party," which begins its second season on VH1 at 10 p.m. on Oct 16 — to come by for a visit.

"He was in New York last week," Stewart says. "I tried to get tickets for my friends. I was in Maine. And I never heard from Snoop. He never answered me. Snoop!" she says, mock outrage in her voice. "Why would you do such a thing? Snoop!"

And then: "Have you seen the promo for the show? We did a spoof on 'Ghost.' "

(Wondering just how fabulous it is? Take a look:)

Stewart says "Pot Luck Dinner Party" — in which she and Snoop cook and invite celebrities to enjoy the party and some double entendres — works because "it's unexpected. It's a strange combination of talent. It's not a cutthroat competition. It's not a silly people who don't know anything kind of show. Snoop's extremely talented, both in music ... he's actually a good cook."

And no, Snoop hasn't persuaded her to smoke pot. “I don’t eat marijuana and I don’t smoke marijuana,'' Stewart says. "I'm kind of allergic to smoke, so I don't like smoky things. That kind of fits in that category."

We chat about guilty pleasures. I tell Stewart I like those pickled eggs you see in big jars in old time bars. She calls me a "poor girl."

She says she doesn't have many guilty pleasures. "I’m not a closet snacker. I don’t have to have a drink before I go to bed. I actually have never had a drink in my house by myself. Ever. ... I have friends who light a candle and take a bottle of wine and go sit down in a chair. I have never done that in my life. ... That's not fun for me. It wouldn't be fun at all. I don't have to drink. I can pet my cat."
